I would imagine he will sit in front of the TV as long as you let him. Something called "tough love" needs to come into play here. I don't know how you will manage it, but you need to make time for yourself. And you need to let him do some things for YOU. As long as you pamper him and give in to every mood, you are not really doing him any favors, and as good as it feels at the moment to do something positive and concrete to make his journey a little smoother, there comes a time when you have to let go of the reins and let him drive the horse and buggy some!! I am suggesting you try it, gently at first, and see how things go.
Good luck , it sounds like you have been a great help to him when he needed it the most. Now that he is better, ease up on yourself!!
